Overview

AI-generated overview

A local MCP server that gives an assistant a single interface to work with around 20 different database systems.

What you can do
Polyglot Database MCP presents one unified MCP interface for roughly 20 databases, including SurrealDB, ArangoDB, Virtuoso, and CouchDB. The registry description does not list individual tools, so the exact operations exposed are not documented here. It runs as a local process over stdio, so the assistant talks to it on the same machine rather than to a hosted endpoint.
When to use it
Worth considering when you work across several database engines and want one assistant integration instead of a separate server per database. It is a poor fit if you only use one database, since a dedicated server would be simpler.
Requirements
Runs as a local process over stdio, distributed as an OCI image (ghcr.io/hyperpolymath/poly-db-mcp:main), so a container runtime is needed. Desktop only; no web executable. No authentication, environment variables, or headers are declared, but connecting to real databases would still require connection details and credentials supplied some other way.
Before you install
No credentials, environment variables, or headers are declared, so how database connection secrets are passed is undocumented; treat any connection strings or passwords you supply as sensitive. The tool list is not published, so what the server can read, write, or delete in your databases is unknown before install. It is desktop-only and not available as a web executable.

Installation

In SourceWeft

  1. Open Polyglot Database MCP in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Desktop only via STDIO. STDIO servers start a local process, so they need the SourceWeft desktop host.

Score

25% of the applicable checks met

How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.

  • Reached in the last 30 days25 pts

    Keep the endpoint answering the MCP handshake; SourceWeft probes it every 30 days.

  • Auth declared10 pts

    Declare the credential headers in the registry entry, or keep the endpoint answering the probe so its auth can be classified.

  • Tools listed15 pts

    Answer tools/list without a credential, or ship a package that starts in a sandbox without one.
